Appllcation filed August 23, 1909. Serial No. 514,210.

To all whom, it may concern:

Be it known that 1', ISAAC S. DEMENT, a

i citizen of the United States, and a resident of St. Nicholas, in thecounty of Duval and State of Florida, have invented certain new anduseful Improvements in Printing- Wheels, of which the following, whentaken 1n connection with the drawing accompanying and forming a parthereof, a full and complete description, sufficient to enable thoseskilled in the art to which it pertains to understand, make, and use thesame.

This invention relates to printing wheels used in registering, dating,numbering, adding and other like machines The object of the invention isto obtain, at small cost, a printing wheel (provided with characters 0..the periphery thereof) which will be light in weight and durable;

and also to obtain a printing wheel, which will, when made in largequantities, be accurately constructed, so that one thereof will be theduplicate of the others.

In the drawing referredto I have illus trated a device embodying myinvention providedwvith numerals from one to zero on the peripherythereof and in which draw- Figure I is the front viewof a blank fromwhich one member of the device is obtained. Fig". 2 is an edge elevationof the blank illust 'ated in Fig. 1. Fig. 3 is a front view ofthe'member of the device which is obtained from the blank illustrated inFigs. 1 and 2. Fig. 4. is a front view of a blank from which anadditional member of the device embodying th'e invention obtaiiied. Fig.5 is a front view of the member obtained from the blank illustrated in Fig. 4, joined to the member illustratcdin Fig. 3. Fig. (3 is a verticalsectional view of a device embodying the invention on lines 6-6 of Fig.5, viewed in the direction indicated-by the arrows, and Fig 7 is aperspective of a comb provided with fingers, by means of which fingers aplurality of the devices embodying this invention may be actuated in adetermined order.

A reference letter applied to indicate a given part is used to designatesuch part throughout the severalfigures of the draw,- ing, wherever thesame appears.

'A is a blank provided with'the central aperture a, a, and with theperipheral logs or cars B. As many lugs or cars B are made to blank A asare desired. Usually the number thereof corresponds with the number ofcharacters on the periphery of the device.

1, 2, 3, l, 5, 6 7, 8, 9, 0, (Fig. 1), are the characters which appearon the )eriphery of the device in the construction illustrated in thedrawing. These numerals are shown as raised, as appears from the partslettered X, in Figs. 2, 3, 5 and 6 of the drawing. The broken lines C-C,Fig. 1 indicate the lines on which the several ears B are bent to lie atsubstantially right angles to the remain or of the blank A in thecomplete device. I

D, Fig. l, is a blank from which one mem ber of the device is obtained.

(l is an aperture in blank I) and d is a tongue made in the cutting outof the aperture in the blank.

E is a notch or recess on the peripheral v edge of blank D.

formed up on line C the tongue d is bent on line Z) to substantiallyright angles with the plane in which 'lhe part of the blank D which isbetween the lines C and the aper-- ture cl, lies.

When the member obtained from the blank D is forced into its determinedposition relative to the member obtained from the blank A. the end ofthe tongue d, is contained in part a of aperture a, a, of blank A; andthe recess'la of blank D is between a determined pair of the ears B, B.F, Fig. 7, is a comb provided with fingers f. Comb F is designed to bemoved reciprocally and actuate one or a plurality of the devicesembodying this invention, in a determined manner. With this in view thef ffiofthe fingers are shaped 'so that onethereof may rest on t- 1eperiphery of one (if the plurality of devices which arerotatablyfmounted on shaft Gm The recess E is made so that whenthedevice is actuated by. one of the fingers of the comb illustrated inFig. 2 and the next adjacent wheel is also to be actuated the fingeractuating-the wheel of highest denomination is theshortest op of thewheels actuated thereby and "move sucli wheels to bring the zero thereofinto the Zprinting line. corresponds with what is termed the deep notchin theordinary counting wheels of a series which are actuated by thefingers of a comb. I

The members obtained from blanlrsA- and D may, be joined permanently byforcing them together as hereinbefore described, when made of sheetsteel or other like metal, and, in addition thereto, when such membersare made of sheet brass or other like metal, they may be soldered orbrazed together.

Having thus described my invention what I claim as new and desire tosecure by Let ters Patent iS 1. In a printing wheel, a sheet metalmember provided with. a body portion, and providedwith a plurality oflugs arranged in planes which are concentric to the axis oi thewheel,in. combination with an additional member joined to the first namedmember, said additional member provided with an annular'fiange having anaperture theretl'irough, said members respectively provided withapertures concentric to said axis. a

2. In a printing wheel, a sheet metal .member provided with. a bodyportion, and provided with a plurality of lugs arranged in planes whichare concentric to the axis of the wheel, in combination with anadditional member joined to the first named member, such membersrespectively provided with apertures concentric to such axis, and a toue forced out from one of such members and arranged to connect themembers adjaccntto the concentric apertures.

3. In a printing wheel, a sheet metal'rnember provided with a bodyportion, and prothe first named member, such members rep The recess Etherefore provided with a tongue forced out therefrom and arranged toconnect the members adgac ent to'the concentric a ertures.

4. In a printing wheel 'a sheet metal member provided with a bodyportion and provided with a pluralityofflltugs respectively arranged inplanes which are concentric to the axis of the wheel, in combinationwith an additional sheet metal member provided with a body portion andwith a cylindrical portion,

such cylindrical portion having an aperture therethrough, such membersoined together so that the cylindrical portion of the lastnamed-member'forms the periphery of the l wheel between the lugs of thefirst named member and the aperture in the cylindrical portion arrangedto come between two of suchlugs, and such members provided withapertures concentric with the axis, of the Wheel.

5. In a printing wheel a sheet metal member provided with a body portionand providcd with a plurality of lugs respectively arranged in planeswhich are concentric to the axis of the wheel, in combination with anadditional sheet metal member provided with a body portion and with acylindrical portion, such cylindricalportio-n having anaperturetherethrough, such members joined together so that thecylindrical portion of 'the'last named member forms the periphery of thewheel between the lugs of the first.
